13. Evaluation of vitamin D plasma levels after mild exposure to the sun with photoprotection
Abstract: Background: Most of the organism’s vitamin D (VD) is obtained through the cutaneous synthesis after exposure to the sun’s UVB radiation. Sunscreens are indicated for the prevention of actinic damage to the skin, however, there are few clinical trials assessing the synthesis of cutaneous VD in real-life situations of sun exposure with ordinary

14. Decreased muscle strength is associated with proinflammatory cytokines but not testosterone levels in men with diabetes
The aim of this study was to compare muscle strength in male subjects with type 2 diabetes mellitus (DM2) with and without low plasma testosterone levels and assess the relationship between muscle strength, testosterone levels, and proinflammatory cytokines. Males (75) aged between 18 and 65 years were divided into 3 groups: control group that did not have d

15. Long non-coding RNA-ROR aggravates myocardial ischemia/reperfusion injury
Long non-coding RNAs (lncRNAs) play an important role in the pathogenesis of cardiovascular diseases, especially in myocardial infarction and ischemia/reperfusion (I/R). However, the underlying molecular mechanism remains unclear. In this study, we determined the role and the possible underlying molecular mechanism of lncRNA-ROR in myocardial I/R injury. H9c

16. Assessing endocrine and immune parameters in human immunodeficiency virus-infected patients before and after the immune reconstitution inflammatory syndrome
ABSTRACT Objective The present study compares immune and endocrine parameters between HIV-infected patients who underwent the Immune Reconstitution Inflammatory Syndrome (IRIS-P) during antiretroviral therapy (ART) and HIV-patients who did not undergo the syndrome (non-IRIS-P). Materials and methods Blood samples were obtained from 31 HIV-infected patients

17. High prevalence of insulin resistance among Brazilian chronic hepatitis C patients
ABSTRACT Objective: This study aims to estimate the prevalence of insulin resistance (IR) among chronic hepatitis C (CHC) patients and their related laboratory and demographic data. Subjects and methods: In this study, non-diabetic CHC patients referred to Viral Hepatitis Ambulatories from Rio de Janeiro (Brazil) donated blood samples. Insulin was measured

18. Prevalence of Trypanosoma cruzi/HIV coinfection in southern Brazil
Abstract Chagas disease reactivation has been a defining condition for acquired immune deficiency syndrome in Brazil for individuals coinfected with Trypanosoma cruzi and HIV since 2004. Although the first coinfection case was reported in the 1980s, its prevalence has not been firmly established. In order to know coinfection prevalence, a cross-sectional stu

19. Oxidative stress in sepsis. Possible production of free radicals through an erythrocyte-mediated positive feedback mechanism
Abstract Background: Sepsis is an illness with a high morbidity for which no effective treatment exists. Its treatment has a high cost because it usually requires an intensive care unit and expensive antibiotics. The present study focus in the production of reactive oxygen species in the early stages of sepsis. This study aimed at investigating the producti

20. Electrochemiluminescence Sensor for the Detection of Tiapride Hydrochloride with Chitosan-Ru(bpy)32+-SiO2NPs/MCNT/Nafion Modified Electrode
Chitosan-Ru2(bpy)32+-SiO2 composite nanoparticles (CRuS NPs) were prepared by reverse microemulsion method for the electronic attraction between negative charge of hydroxyl groups in chitosan and positive charge in Ru2(bpy)3 2+. Based on the multi-walled carbon nanotubes (MCNT)/Nafion composite membrane technology, CRuS NPs was effectively and steadily immob

21. Effects of perinatal exposure to nonylphenol on delivery outcomes of pregnant rats and inflammatory hepatic injury in newborn rats
The current study aimed to investigate the effects of perinatal exposure to nonylphenol (NP) on delivery outcome of pregnant rats and subsequent inflammatory hepatic injury in newborn rats. The pregnant rats were divided into 2 groups: control group (corn oil) and NP exposure group. Thirty-four pregnant rats were administered NP or corn oil by gavage from th

22. Methylene Blue to Treat Protamine-induced Anaphylaxis Reactions. An Experimental Study in Pigs
ABSTRACT Objective: To examine if methylene blue (MB) can counteract or prevent protamine (P) cardiovascular effects. Methods: The protocol included five heparinized pig groups: Group Sham -without any drug; Group MB - MB 3 mg/kg infusion; Group P - protamine; Group P/MB - MB after protamine; Group MB/P - MB before protamine. Nitric oxide levels were obtai

23. Determination of Aspirin Using Chemiluminescence System of Tris(1,10 phenanthroline)Ruthenium(II)-Cerium(IV)
A new chemiluminescence (CL) method has been proposed for the simple determination of aspirin (acetylsalicylic acid, ASA). The method is based on the enhancement effect of ASA in the CL reaction of tris(1,10 phenanthroline)ruthenium(II), Ru(phen)32+, with cerium(IV) (CeIV) in acidic medium. Under optimum conditions, the CL intensity was proportional to the c
